Your B&K's are great for older formats, and if your Sony has analog out, it will be fine for HD formats.
I dont know much about your speakers & sub, but I do know I like dynamic speakers for HT. Hard to beat Kkipsch reference. You could almost get Klipsch KLF 30's, 20's, and the C7 for just over 1500. If you upgraded their tweeter diaphrams from Crites to titanium(another 160 aprox) your theater would rock.
I have owned all the Logans. They will play loud with a good amp, but their dynamics stink IMO. I now use the KLF setup, and smile with every movie.
Again I am not familiar with your speakers.
I also prefer 2-4 quality subs that may have less spl, but go deep, verses 1 monster sub in one location.
